First Alert Forecast: Trade Wind Weather Weekend

HONOLULU (HawaiiNewsNow) – A strong area of high pressure north of Hawaii is going to push steady winds across the islands through the weekend and early next week, so expect it to be breezy—perfect time to secure any loose items outside. However: extra moisture is moving in tonight into tomorrow morning, so if you live on the windward side or in the mountains, get ready for more rain. Around the middle of next week, that pressure system shifts away and a low-pressure system might develop nearby, which will calm those winds down a bit.

Right now, some scattered showers are moving across the windward side, with the Big Island getting hit the hardest, but don’t worry—the strong winds from the north will keep things pretty typical for summer through early next week.

However, starting Sunday, more moisture is moving in, which means you’ll see more rain showers and they’ll be stronger, and this time some rain might even reach the leeward side where it normally doesn’t rain as much. Here’s the bigger picture: later next week, that high-pressure system up north is going to weaken and shift, and at the same time, tropical systems might start developing southwest of Hawaii—basically, there could be some tropical activity brewing, but it’s too early to know if it’ll actually affect the islands, so stay tuned for updates.

The current small medium-period south-southwest swell will hold today just below the summer average. A small to moderate, long-period southwest swell is expected to fill in late today through Monday, which will boost surf through early next week. Surf along east-facing shores will remain rough and choppy through the forecast period as fresh to strong trades hold. A series of small, moderate period west swells will hold into early next week, sourced from Typhoon Bavi in the far western Pacific. No significant north or northwest swell are expected, so surf along north- facing shores is expected to remain flat to tiny.
